3 way crossover design software12/31/2022 ![]() ![]() The capacitor on the tweeter is just there for tweeter protection with a DSP based crossover (or that was my intention after seeing this: ). Since I have not considered the waveguided version of the tweeter, it seems it little difficult if I push the crossover between mid-tweeter higher (or I don't know yet how to do it well yet). The acoustical crossover point in the attached plot above looks to be around 360 Hz between woofer and mid (based on the traced SPLs)Ģ) I also wanted to get the directivity of the mid and the tweeter to match as much as possible during the handoff. For example the measurements here ( ) for the (almost same NBAC version) midrange driver I used above is the best in the band 200Hz to 3kHz. Regarding your questions,ġ) I have used fourth order electrical on the midwoofer to let it play in the region where its harmonic distortion performance is the best. The design criteria that I wanted to follow in this setup is to ensure low distortion in each drivers passband and smooth directivity to the extent possible. I am going full DSP-based on the crossover (on woofer, mids, and tweeter). Looking forward to learn more from your valuable opinions.Ĭlick to expand.Hi. I would like to know more details about how should I look at the driver phase matching, can I get better directivity curve for this system, get better on/off axis response etc and in general any advice to better the performance is welcome. The vituixCAD six pack showing resultant system response details is also attached. With my limited knowledge, I have tried to design a crossover for this system as shown in attached image. (Just for more details, the woofer is assumed to be put in sealed box of size 55L, midrange also in a sealed enclosure of about 12 L). The simulations that I have attached along with this post have these drivers placed on a baffle of width 32cm and height 105 cm (with 20mm edge rounding for easing diffraction-related anomalies), currently at locations mentioned in the crossover image. Since this is more of an academic exercise for now, I have generated the crossover configuration based on traced SPLs of these drivers from their datasheets ( know that ideally, we should put the drivers in the cabinet and then take measurements and then design crossover based on it) I have selected the drivers for this project (I have these drivers with me) as I wanted to study designing a DSP-based 3 way crossover in VituixCAD. ![]()
